How do I open note track to use piano

I’m trying to make a note track to use the midi controller what do I do?

Audacity isn’t a MIDI application. It has some VERY limited MIDI capabilities. You can open a MIDI file, maybe do some limited editing, and I think you can play it (using whatever virtual instruments are built-into Windows).

It can’t record/capture MIDI messages from a MIDI keyboard.
